Sri Lanka Travel from Arugam Bay to Pasikudah

I have planned an extensive trip around Sri Lanka. We are hiring a van and driver for the trip and part of itinerary involves a trip up the east coast. Would anyone know how long it would take to go from Arugam Bay to Pasikudah. We are traveling with 2 children (5 and 7). If it going to be too long, we would consider a stopover, but can’t seem to find any hotels on the route. Could anyone help.
Thanks

The A4 coastal road from Arugam Bay up to Valaichchenai (a few km from Pasikudah) was upgraded a few years ago, so you shouldn’t have any issues with bad road surfaces. It’s about 150km from Arugam Bay to Pasikudah, so – if the traffic’s good – you should get there within three hours and shouldn’t need an overnight stopover.
